Kev Tshawb Fawb Daim Ntawv Thov CAS: 5550-08-3|9, 9-Diphenyl-9H-9- silafluorene

1. Homolytic Aromatic Hloov thiab Cyclization

9-Silafluorenes, suav nrog 9H-9-silafluorene, 9,9-diphenyl-, yog tau los ntawm kev hloov pauv-hlau-dawb intramolecular radical silylation ntawm 2-diphenylsilylbiaryls ntawm lub hauv paus-promoted homolytic aromatic hloov. Cov txheej txheem no yog catalyzed los ntawm electron thiab yog ib qho tseem ceeb rau synthesizing silafluorene derivatives zoo thiab sustainably (Leifert & Studer, 2015).

2. Daim ntawv thov Solid-State Fluorescence

9H-9-Silafluorene derivatives ua kom pom cov khoom muaj zog-state fluorescence tshwj xeeb. Kev hloov pauv ntawm 9- txoj haujlwm tseem ceeb cuam tshuam rau lawv qhov nqus thiab emission spectra, uas yog qhov tseem ceeb rau kev tsim cov ntaub ntawv nrog cov khoom siv kho qhov muag (Yamanoi li al., 2016).

3. Luminescent Probes hauv Aqueous Solutions

Silafluorenes nrog cov khoom siv tshwj xeeb, xws li 9, 9-diphenyl, pom muaj zog emissivity thiab siab quantum yields hauv cov kuab tshuaj organic. Lawv solubility thiab luminescence nyob rau hauv cov kev daws teeb meem aqueous ua rau lawv muaj peev xwm sib tw rau kev siv tshuaj lom neeg thiab kev lag luam, tshwj xeeb tshaj yog nyob rau hauv kev kuaj xyuas thiab ua kom pom cov qauv lipophilic (Spikes li al., 2021).

4. Ring-Closure Reaction thiab Crystalline tsim

Kev tsim ntawm silafluorene los ntawm intramolecular nplhaib-kaw cov tshuaj tiv thaiv yog lwm qhov chaw siv tseem ceeb. Cov tshuaj tiv thaiv no feem ntau ua rau cov crystalline silafluorene derivatives heev, uas tuaj yeem ua tau los ntawm ntau txoj kev spectroscopic rau kev siv ntxiv (Millevolte li al., 1997).

5. Fluorescence hauv Doped Polymer Films

9H-9-Silafluorene, 9,9-diphenyl-derivatives tau tshawb xyuas rau lawv cov peev xwm siv hauv cov khoom siv hluav taws xob, tshwj xeeb hauv kev tsim OLEDs thiab bioimaging. Lawv qhov tshwj xeeb photophysical zog, xws li fluorescence solvatochromism thiab fluorescence npaum nyob rau hauv doped polymer films, yog qhov tseem ceeb (Pusztai li al., 2013).
